This. invention relates to window operating @devices, and particularlyto power operated devices ..-for.raising and lowering automobileWindows.

Various types of power operated devices for raising and loweringautomobile windowshave been proposed. Some are effective for theirintended-purpose, but all have limitations, some of which are serious.Thus, it is customary to elimiiinatemanually operable window operatingmeans -orflto provide them in normally disengaged rela- Ltion. Inthecase of devices of the vacuum operuated type which lack manuallyoperable means, it -isnecessary that the automobile engine be .operatingbefore the windows can be raised or lowered. Of greatest importance,however, is the fact that the lack of provision for manualoperav.tion-of the windows presents a serious hazard in case of anaccident which disables the power operated device and in which theautomobile doors become jammed. Thus, in case of an upset, it .maynot bepossible to open the cardoors or to .-..energize the window operatingdevice. The ocacupants of the automobile will therefore be trapped. Thehazard involved becomes most evident when it is considered that firesfrequently efollow and result from serious accidents such .as.-:collisions and upsets. The same hazards. occur .Where. normallydisengaged manually operable means are provided, to at least someextent, be- -causeof the difiiculty of. adjusting themeans to.cpperative position and simultaneously, operating -.the same.

.The primary object of this invention is to pro- ..videa power actuatedwindow operator and .an sauxiliary; manually controlled operator, inwhich v.the ,power .actuated device automatically dise-jengages themanual device upon actuation thereof and automatically re-engages saidmanual device .upon de-energization thereof.

- .,Otherobjects will be apparent from the description and appendedclaims.

lower the window 20. This combination and arouter shape. A secondcup-shaped clutch me'mber 84 has peripheral clutch teeth 80complementary to and adapted to interengage withthe teeth of member H3.The clutch member 84has a contoured central opening conforming with the4 times the device is conditioned for operation by the crank.Specifically, rotation of crank 18 frees spring H4 from housing H2 andat the same time rotates shaft 14 through engagement of tongue H8 offitting H6 with a side wall of the tongue-receiving groove in hub H0. Asthe shaft 14 rotates, the sleeve 82 also rotates by vir- 'tue. of itspinned connection at 88. The clutch element keyed on said sleeve drivesthe clutch element 18 and associated pinion l8. Consequently, thewindow-operating lever 26 which mounts gear segment 42 is operated toraise or rangement of parts insures that means for operating the windoware provided under all normal conditions and satisfies the requirementsfor a safe ready-to-operate manual device and the convenience of apower-operated device.

It will be understood that the construction herein described andillustrated constitutes the preferred embodiment of the invention,and-that of the appended claims and the spirit jacent to the housing 92and is connected by a two opposed operating positions. The diaphragmunit includes an elongated arm [00 which is responsive to actuation ofthe diaphragm unit.

Arm I08 extends freely through the clutch housing opening 94 and isfulcrumed thereon at H34.

other embodiments which fall within the' scope of the invention arecontemplated. I

I claim:

1. In a cross arm window fluid regulator system, said crossed arms beingin a vertical plane and hingedly connected together, one of the armsinclining downwardly and forwardly and being of greater length than theother arm, a vertically disposed pressure cylinder beneath the outer endof the downwardly and forwardly inclined arm, the lower end of saidcylinder being hingedly anchored, a piston slidably mounted in saidcylinder, a piston rod carried by said piston and extending upwardly andhingedly connected to-the forwardly inclined arm at its outer end, saidforwardly inclined arm being pivotally mounted The inner arm I00 engagesagainst peripheral I 1 l4 encircles the hub I I0 and said fitting partand" is adapted, upon rotation of crank N28, to effect a clutcheddriving connection between the crank and the shaft through the fittingH6 while preventing rotation of the crank in the event of rotation ofthe shaft 74 by other means. This spring clutch arrangement is of thetype conventionally used for operating automobile windows.

The operation of this part of the device is as follows: When the valve52 is adjusted to operating position by control 56 when the automobileengine is operating, the diaphragm unit 96 is subjected to a suctionaction which rocks the arm I00 upon the fulcrum I82 and thereby pressesagainst the flange I06 of clutch element 84 to disengage the clutchteeth 88. Thus the pinion 16 is free to rotate about the shaft 14 whilethe power unit 48 is actuated to raise or lower the window 20. Duringthis time the'spring H4, being expanded in housing H2, holds the shaft14 and crank I88 stationary. When the valve is re set at its neutralposition, thus deenergizing the diaphragm unit 96, the spring 90 returnsthe clutch member 84 to clutched engagement with member 18.Consequently, whenever the power unit 48 operates, the crank Hi8 remainsstation my and it does not become a hazard. At all other e for a rockingoperation in a vertical plane, a gear segment carried by said forwardlyinclined arm, a rotatable shaft for manual operation of the cross armswhen pressure is not being used, 'a crank carried by said shaft, apinion rotatably carried by the shaft and meshing with the gear segment,a clutch element carried by the pinion, a clutch element slidably on androtatable with said shaft, means for supplying pressure to opposite endsof the cylinder, a three-way valve. said three-way valve cooperatingwith the pressure supply means for reciprocating the piston in thecylinder, a pressure controlled diaphragm a rock lever connectionbetween the diaphragm and the clutch for clutching and declutchingoperations and means for supplying pressure to the diaphragm through thethree-way valve and declutching clutch members after a window adjustingoperation.

2. A device as set forth in claim 1 including means for controlling thethree-way valve from a position remote in relation to the valve;
